What does unlimited mean?
Total: one allowance for the validity period. Daily: an allowance each day, continuation after use unconfirmed. Reduced speed: stays connected at a lower speed after the high-speed allowance. No throttling: explicitly no usage-based speed reduction. Fixed speed: a speed cap from the start. Policy unavailable: unlimited data confirmed, speed rules unknown. No throttling does not guarantee network speed.

Common questions about South Korea eSIMs
Which networks will a South Korea eSIM connect to?
Plans for South Korea sold here connect to SKTelecom / LG Uplus / Telkomsel / XL / AXIS / Smartfren / Indosat Ooredoo / 3 / LG U+ / SK Telecom. Speed depends on the signal where you are standing and how busy the local cell is — who you buy from does not change it.
How much does a South Korea eSIM cost?
There are 42 plans for South Korea right now, priced from 0.60 USD to 34.00 USD. Where you land depends on the data and validity you pick.
Are there unlimited plans for South Korea?
There are no truly unlimited South Korea plans here, but there are throttled-unlimited ones: once the high-speed allowance is used, the connection slows down instead of stopping. Each plan states its reduced speed under "speed after the allowance".
How many days can a South Korea eSIM cover?
Anywhere from 1 to 30 days. Validity only starts once you arrive and the eSIM actually connects to a network, so installing before you fly costs you nothing.
